Everything I've said about weed on here, I don't think anyone would disagree on one point: for an addict, smoking weed is NOT active recovery. Its going to lead back to his doc if it hasn't already. A characteristic of TRUE recovery is someone making their old life fit the program, not the other way around. I.e. when my brother got home (the 1st/semi successful time) he didn't make sobriety fit with his old job, friends, girlfriend, etc. He made his life fit with the program. Hung out with new drug free people, at new drug free places, and worked a new drug free job, etc.
To me, it looks like he wants it, but not bad enough. Not bad enough to say "I can't do it my way, I'm going to start my life from scratch cause its worth it." and personally, that's the only way i've seen it work. and even then...
I may be wrong. This is my humble opinion. Good luck.
